Multi-agent system is continuously utilized in e-Business that want to improve responsiveness and efficiency of systems. In this paper, we propose multi-agent-system and various techniques that are Web service, ontology, and data mining techniques. The multi agent system, which constitutes the backbone of the framework, connects these pieces together and makes them perform properly. JADE is the MAS platform implemented this project. JADE is quite easy to learn and use. Moreover, it supports many agent approaches such as agent communication, protocol, behavior and ontology. This framework has been experimented and evaluated in the realization of a simple, but realistic, prototype of an e-Wedding system. The results, though still preliminary, are quite encouraging.

To face current socio-economic adverse conditions enterprises must increase their efficiency and evolve to the requirements of customization and sustainability. Modern production systems need to deal with instability of markets and resource scarcity regarding an economical, ecological and social concern. The Evolvable Production Systems (EPS) has aimed at developing such technological solutions and support mechanisms that may endow European assembly companies to fulfil these demands. EPS seeks highly adaptable control and mechanical systems enhancing re-usability and interoperability of modules, extending their life cycle and enabling short deployment times at shop floor level. Only with very agile and adaptable systems will be possible to enhance material re-usability, reduce energy consumption and give a quick response to unforeseen changed conditions or new business opportunities. This paper will present Evolvable Production Systems advantages in order to achieve such results towards more ecological and economically suitable production systems.

Agent technology plays an important role in the construction of context-aware AmI environments, providing the means to develop intelligent, proactive, autonomous, and interacting systems, able to adapt their behaviour according to some contextual conditions. However, the development of modular context-aware agents has been a challenge to software engineers, since context-awareness use to have influence in several components of the agent architecture, increasing their complexity and making them difficult to evolve and reuse. In order to improve the modularization and development of context-aware agents for AmI applications, this work proposes the application of aspect-orientation to separate all the issues related to context-awareness inside the agent software architecture. Specifically, our approach focuses on the modularization of context-awareness as aspects for Malaca software agents. The application of aspect-orientation leads to separate in aspects all the agent functions related to context-awareness, such as context acquisition and context-dependent behaviour, improving the internal modularization of context-awareness in the agent architecture and making it able to adapt dynamically to different contexts.

This paper outlines why market development efforts could fail by choosing contract logistics providers. This is usually due to the nonexistence of marketing capabilities at contract logistics providers. Hence they are not able to deliver effective and service-dominant solutions. The paper points at consequences in preferring contract logistics providers by comparing them with demand chain leaders which capture marketing as well as logistics capabilities and therefore are being able to offer state-of-the-art business concepts.

In extended enterprises, real-time manufacturing information tracking plays an important role and aims to provide the right information to the right person at the right time in the right format to achieve optimal production management among the involved enterprises. This paper proposes a RFID-enabled real-time manufacturing information tracking infrastructure to address the real-time manufacturing data capturing and manufacturing information processing methods for extended enterprises. Following the proposed infrastructure, the traditional manufacturing resources such as employees, machines and materials are quipped with RFID devices to build the real-time data capturing environment. Then, a series of manufacturing information processing methods such as manufacturing cost, progress, WIP (Work-in-progress) inventory etc. are established to track the real-time manufacturing information of extended enterprises. Finally, a case study is given to demonstrate the presented framework and corresponding methodologies.

Due to the complexity of freeform surface machining, multi-axes machine tools are widely used to increase the precision of surface machining. There are needs for the user, designer and manufacturer of machine tool constructing the multi-axis machine tools with various configurations by the virtual reality technique. The damage of multi-axis machine tool due to collision can be prevented by virtual machine tool simulation. The machining information, such as the machining time, machining accuracy and the NC codes that cause collisions, can be obtained before actual machining. Most of the previous research of postprocessor concentrated on the orthogonal and single configurations. This paper aims at developing an automated universal postprocessor for both orthogonal and nonorthogonal configurations. The configuration information of machine tools and modified D-H notation is employed to develop the postprocessor of multi-axes machine tools. The user interface of the system has been implemented and displayed by OpenGL. A case study is given to demonstrate the construction procedure of virtual machine tool. Finally, the NC program converted from the developed postprocessor has been verified with commercial software.

Integration of the measurement activity into the production process is an essential rule in digital enterprise technology, especially for large volume product manufacturing, such as aerospace, shipbuilding, power generation and automotive industries. Measurement resource planning is a structured method of selecting and deploying necessary measurement resources to implement quality aims of product development. In this research, a new mapping approach for measurement resource planning is proposed. Firstly, quality aims are identified in the form of a number of specifications and engineering requirements of one quality characteristics (QCs) at a specific stage of product life cycle, and also measurement systems are classified according to the attribute of QCs. Secondly, a matrix mapping approach for measurement resource planning is outlined together with an optimization algorithm for combination between quality aims and measurement systems. Finally, the proposed methodology has been studied in shipbuilding to solve the problem of measurement resource planning, by which the measurement resources are deployed to satisfy all the quality aims.

Current major road mapping efforts, such as ManuFuture, Fut Man and EUPASS, have all clearly underlined that true industrial sustainability will require far higher levels of systems' autonomy and adaptability. In accordance with these recommendations, the Evolvable Production Systems (EPS) has aimed at developing such technological solutions and support mechanisms. Since its inception in 2002 as a next generation of production systems, the concept is being further developed and tested to emerge as a production system paradigm. The essence of evolvability resides not only in the ability of system components to adapt to the changing conditions of operation, but also to assist in the evolution of these components in time such that processes may become self-X, x standing for one more desirable properties of a system subjected to a variable operation condition such as self-evolvable, self-reconfigurable, self-tuning, self-diagnosing, etc. Characteristically, Evolvable systems have distributed control, and are composed of intelligent modules integrated. To assist the development and life cycle issues, comprehensive methodological framework is being developed. A concerted effort is being exerted through European research projects in collaboration with European manufacturers, technology/equipment suppliers, and universities. After briefly stating the fundamental concepts of EPS, this paper presents current developments and applications.

This article presents a framework based on agent concepts and REST architectural style. Based on this framework, an agent virtual machine along with its operational semantics are introduced. The idea is to consider agents' actions as manipulation of resources within environments using only a limited set of primitives. This makes both the agent abstract machine and its operational semantics easy to comprehend and the implementation straightforward. Finally, performances of our implementation are evaluated using a simple benchmark application.

Over the past few years, approaches including artificial intelligence models into Wireless Sensor Networks have gained much attention within the research community. However, little attention has been paid to integrate Fuzzy Rule Based-Systems into Wireless Sensor Network. Since traditional approaches of Fuzzy Rule Based-Systems cannot be applied, due to limited resources that the sensors nodes have, the principal aim of this work is to design a distributed knowledge based Wireless Sensor Network, where each node of the network executes an adapted Fuzzy Rule Based-System. This aim has been divided into the followings: 1) to design a Fuzzy Rule Based-System adapted to a sensor node, 2) to design an application protocol which allows transmitting knowledge bases to sensors nodes and 3) to simulate a particular scenario with network simulator ns-2. The performance of a Sun SPOT sensor has been evaluated and a comparison to other devices is reported. The results show that a Sun SPOT sensor can execute properly a Fuzzy Rule Based-System adapted to it, and that it is possible to create a useful distributed knowledge based Wireless Sensor Network.
